Wolf Man

Wolf Man was Ame and Yuki's father, and the husband of Hana, who became a widow after his death. He had the ability to transform into a wolf; this ability was genetically passed to his children.

The cause of his death was by falling down in a canal whilst preying for a bird.

Little is known about Wolf Man. He seemed to be a calm but nice man who was shown to have a strong paternal instinct, probably due to his wolf instinct. Like any other wolf or wild animal, he preyed for food, for the survival of his mate and offspring.

Human form
In his human form, Wolf Man appeared to be a tall man with a slim build. He had short black hair with a bang and blue eyes.

Wolf form
In his wolf form, Wolf Man appeared to be an adult wolf with black, grey and white fur. The fur on his head resembled his hairstyle as a human. He had blue eyes.

Clothing
As a human, Wolf Man usually beared a white shirt with dark blue sweatpants. Outside, he wore a black winter coat with a white fur collar, with his white shirt underneath.

As a wolf, he didn't wear any clothing, except when he turned into a wolf for the first time in front of Hana, where he kept his winter coat and shirt on whilst transforming.
